Life as we know it is a process running on a substrate of carbon-based molecules. It is not impossible or inconceivable that in other places at other times the process of Life can and does run on substrates that are not based on carbon molecules. The silicone-based life form, for example, is a favourite of science fiction writers. But the substrate need not even be material; "virtual"/"notional" substrates are in principle possible.
If Consciousness is a process, what is the substrate? The brain is a possibility. But it is not impossible or inconceivable that substrates outside of / not part of the Body or Mind provide hospitable environments for Consciousness, Mind, Life. Vague and idle speculation here that some of 'this stuff' is involved in such phenomena as telepathy or telekinesis. A strong intuition that consciousness runs on the/a Higgs F/field --- that which binds everything together, the underlying ground of Reality, cf The Hindu concept of Brahman.
The whole of Reality --- material and immaterial / past, present and future / actual and potential --- comprises the universal substrate on which the universal Deity runs --- Deity that is both process and substrate. And neither the name nor even a name for Deity is Jehovah. Ze was/is not the Creator, merely a demiurge, and a self-admittedly wrathful and jealous one at that. Not to mention psychotic enough to demand human sacrifice, eg from Abraham.
